ャネル帯域Ａ，Ｂのホーム側のサーチからやり直す。When an ID other than the quasi-home system is received, and the roaming channel has been registered on the home side of the control channel bands A and B, the roaming channel is set as a communication channel. If the roaming channel has not been registered, a control channel capable of receiving data is set as a communication channel in control channel bands A and B that are not on the home side. If no control channel capable of receiving the line connection control data is found, the search from the home side of the control channel bands A and B is repeated.

In FIG. 4, the home side of the control channel bands A and B is searched, the control channel of the strongest electric field is selected, and then the control channel of the second electric field strength is selected. The line connection control data is received. Further, the control channel bands A and B which are not on the home side are searched, the channel with the strongest electric field is selected, the control channel with the second electric field strength is selected, and the line connection control is performed in the order of the control channels for this search. Performs data reception. At the same time, each control channel number and system ID are stored in the EPROM 4. If the home system ID is not found and the quasi-home system ID is found, the communication channel is set based on the control channel. I other than home system and quasi-home system
If D is found, the call channel is set based on the control channel.

来るようになるという効果を有する。As described above, the cellular telephone device according to the present invention, when receiving a home system ID registered in advance from a cell base station connected by a wireless line, uses a communication channel based on the control channel. When there are a plurality of operation system IDs and the user moves in a plurality of regions having different control channel bands of the IDs, the operation system ID corresponding to the home system ID is set.
This has the effect that the control channel of D is automatically selected with priority and the troublesome selection switching operation is not required. In addition, there is no increase in the call charge (charging) due to a call on the wrong control channel or a call, and the inability to connect to the line after the call is prevented, so that the call operation can be performed easily and reliably. Has an effect.
